METHOD FOR DETERMINING SHARE OF MAIN COMPONENT OF FREE-FLOWING SUBSTANCE WITH USE OF CORIOLIS FLOW METER Russian patent published in 2006 - IPC G01F1/84 

FIELD: engineering of flow meters, possible use for determining share of main component within free-flowing substance.

SUBSTANCE: system, method and software provide for determining of share of main component of free-flowing substance, running through Coriolis flow meter. Electronic circuit receives signals 432 of tension indicators from Coriolis flow meter and temperature signal, which depend on free-flowing substance, running through Coriolis flow meter. Electric circuit processes tensions indicators signals and temperature signal for determining share of main component in free-flowing substance. In one of examples for determining share of main component electronic circuit determines first volumetric flow, based on measured mass flow of free-flowing substance and standard density of main component. Then electric circuit determines second volumetric flow, based on measured volumetric flow, density changed because of temperature and standard density. Electric circuit determines share of main component based on first volumetric flow and second volumetric flow.

EFFECT: increased precision of determining share of main component within free-flowing substance.
